Description

Technical Field

[0001] This utility model relates to an automatic bonding equipment for various types of PCB board reinforcing sheets, belonging to the technical field of chip bonding equipment. Background Technology

[0002] With the trend towards thinner and lighter electronic products and higher-density PCBs, it is necessary to precisely attach reinforcing sheets of various shapes and sizes to specific locations on the circuit board for localized reinforcement.

[0003] In existing technologies, patch bonding is mostly done manually. Traditional manual bonding is inefficient, inaccurate, costly, and difficult to adapt to multi-variety production. Furthermore, manual bonding, being purely manual, is inefficient and cannot guarantee the bonding accuracy of the reinforcing sheets; it also requires manual heating of the reinforcing sheets during bonding, introducing risks during the process; and it consumes a large number of workers. Existing partial automation can only complete the bonding of single-type reinforcing sheets and cannot accommodate multiple types. Therefore, there is a need for an automated bonding equipment for multi-type PCB reinforcing sheets to solve the problems of low bonding efficiency, poor accuracy, and limited product applicability associated with manual bonding of reinforcing sheets to PCBs in existing technologies.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application includes a frame, a PCB mounting board, a reinforcing sheet feeding assembly, and a bonding assembly. The frame has a first feeding station and a second feeding station, wherein the first feeding station is used to place the PCB board, and the second feeding station is used to place the reinforcing sheet.

During the gripping process, the position of the reinforcing sheet is already photographed and positioned by the first positioning camera, ensuring the accuracy of the reinforcing sheet gripping. Then, the attachment head, which holds the reinforcing sheet, moves via a moving unit to the first loading station, i.e., the PCB board, and attaches the reinforcing sheet to the PCB board. Similarly, during this process, the placement position on the PCB board is captured and positioned by a second positioning camera, ensuring the accuracy of the reinforcing sheet's placement. Furthermore, the attachment head, equipped with a heating element, automatically heats the reinforcing sheet during attachment, improving the attachment quality. The automatic PCB board reinforcing sheet bonding equipment of this application can automatically bond the reinforcing sheet without manual bonding, offering high bonding efficiency and precision. The automatic heating of the reinforcing sheet eliminates any safety hazards.

[0017] 2. Based on the foregoing, the carrier of this application is equipped with a carrier drive assembly, which includes a first ball screw pair, a first moving motor, a carrier mounting plate and a cable chain. The carrier mounting plate is slidably mounted on the slide rail by a slider, and the carrier mounting plate is fixedly connected to the nut end of the first ball screw pair. The first moving motor drives the screw to rotate and slide on the slide rail, so as to increase the sliding stroke of the carrier mounting plate through the first ball screw pair, thereby ensuring the relative position of the servo motor and the test camera and improving the accuracy of the photographic test.

[0018] 3. Based on the foregoing, the first loading station of the frame in this application is equipped with a guide rail and a first drive assembly. The first drive assembly includes a first motor, a first drive component, and a first slider. The first loading station is located on the outer side of the frame. The guide rail is fixedly installed on the frame, with one end located at the first loading station and the other end extending horizontally to the middle of the frame, forming a bonding station. The PCB mounting plate is slidably mounted on the guide rail via the first slider. The first motor is fixedly installed on the frame, and its power end is connected to the PCB board via the first drive component. This allows the PCB mounting plate to be slidably mounted on the frame, forming a first loading station for the PCB board and a bonding station for bonding the reinforcing sheet on the frame.

[0019] 4. Based on the foregoing, a third positioning camera is fixedly installed on the frame of this application near the second loading station, forming a reinforcement piece position detection station. This allows the attachment head to be moved to the third positioning camera via a moving unit after it picks up the reinforcement piece. The third positioning camera then takes pictures of the attachment head and the reinforcement piece to determine the posture of the attachment head holding the reinforcement piece. This facilitates adjustment of the reinforcement piece's posture during subsequent attachment to the PCB board, ensuring bonding quality and improving bonding accuracy.

[0020] 5. Based on the foregoing, the second loading station of the frame in this application is equipped with a first mounting frame and a belt loading unit; the belt loading unit includes a belt mounting frame, a belt motor, and a transmission belt; the belt mounting frame is installed on the side of the second loading station of the frame, and one end of it extends to the bonding station of the frame; the transmission belt is rotatably mounted on the belt mounting frame along the belt mounting frame, the belt motor is fixedly mounted on the belt mounting frame, and its power end is connected to the transmission belt; the first mounting frame is installed across the upper side of the transmission belt, and the first positioning camera is fixedly mounted on the first mounting frame. By setting up the belt loading unit, the reinforcing sheet can be loaded manually or by a feeding device, and the subsequent gripping and bonding of the reinforcing sheet does not require manual intervention, thereby reducing the workload of personnel and improving production efficiency.

[0021] 6.

By setting up the waste material chute and the waste material box, during the feeding process of the reinforcing sheet, when the first positioning camera takes pictures for positioning, reinforcing sheets that do not meet the gripping requirements will not be gripped by the bonding head, but will be conveyed to the waste material chute along with the conveyor belt and fall into the waste material box for centralized recycling. At the same time, for reinforcing sheets of different specifications, this application sets up limiting protrusions and encoders to ensure the stability of the reinforcing sheets during the transmission process and controls the belt transmission speed through the encoder to adapt to the bonding requirements required by different specifications of reinforcing sheets, so as to be compatible with multiple specifications of reinforcing sheets and improve the product compatibility of the bonding device of this application.

[0022] 7. Based on the foregoing, the moving unit of this application includes two first-direction slide rails, a second-direction slide rail, a sliding frame, and an attachment head mounting frame, with the first-direction slide rails and the second-direction slide rails arranged perpendicularly to each other.

This allows the attachment head mounting frame to slide in the mutually perpendicular first and second directions, driving the attachment head to attach reinforcing sheets to any position on the PCB board in a horizontal plane. This ensures compatibility with PCB boards of different specifications for reinforcement sheet attachment, resulting in strong product compatibility.

[0023] 8.

This allows the attachment head to adjust the distance between itself and the PCB board radially according to the PCB board specifications and bonding requirements via the fourth motor when bonding the reinforcing sheet, ensuring appropriate bonding force during bonding. To avoid unsuitable posture when gripping the reinforcing sheet for direct bonding, a rotary motor is used to adjust the posture of the reinforcing sheet, ensuring effective bonding.

The second and third drive components in this embodiment are the same as the first drive component, employing a ball screw pair drive mechanism. The ball screw is connected to the motor, and the nut end is connected to the sliding frame / attachment head mounting bracket, which will not be described in detail here.

[0035] In this embodiment, the attachment head 14 is mounted on the attachment head mounting frame 130 via a mounting component, and the second positioning camera 15 is fixedly mounted on the attachment head mounting frame.

[0036] In this embodiment, the first positioning camera 23, the second positioning camera 15, and the third positioning camera 6 are all CCD cameras; the frame is also equipped with a control component, which includes a controller and a barcode scanner; the controller is equipped with a data storage module, and the first positioning camera, the second positioning camera, the third positioning camera, and the barcode scanner are electrically connected to the controller, and the controller is equipped with a data transmission module, which is equipped with a wireless or / and wired transmission interface.

[0037] Working Principle: Before use, the operator of this embodiment of the automatic PCB board reinforcement sheet bonding equipment first determines the type and bonding position of the reinforcement sheet according to the type and specifications of the PCB board. Then, according to the bonding requirements, the feeding speed of the conveyor belt is adjusted by an encoder. In this embodiment, the PCB board is automatically fed by a feeding device, while the reinforcement sheet is manually placed. When the feeding device places the PCB board, a barcode scanner automatically scans the identification code of the PCB board to determine the PCB board specifications and the bonding position of the reinforcement sheet, among other data.

[0038] In operation, the PCB board is placed onto the PCB mounting plate at the first loading station via the feeding device. As the PCB board is placed, a light curtain feedback signal is transmitted to the controller, which then controls the suction fan to adhere the PCB board to the mounting plate. Next, the controller activates the first motor to drive the first drive component, causing the PCB mounting plate to slide along the guide rail to the bonding station. Simultaneously, the operator manually places the reinforcing sheets one by one onto the conveyor belt at the belt mounting frame at the second loading station. The belt motor drives the conveyor belt to rotate, moving the reinforcing sheets towards the bonding station. During loading, when the reinforcing sheet moves to the first positioning camera, the camera takes a picture to determine the type of reinforcing sheet and its placement position on the conveyor belt, and feeds the image data back to the controller. The controller then activates the second and third motors to drive the attachment head mounting frame and sliding frame to slide along the first and second direction slide rails, thereby moving the attachment head to the conveyor belt to pick up the reinforcing sheet.

[0039] After the reinforcing sheet is picked up by the attachment head, the attachment head is moved to the reinforcing sheet position detection station by the moving unit. A third positioning camera takes a picture of the attachment head to determine the posture of the reinforcing sheet when it is attached, and the image data is fed back to the controller. Then, the controller, based on the PCB board specifications and the reinforcing sheet bonding position data, controls the moving unit to slide to the bonding station. A second positioning camera then takes a picture of the PCB board to determine the bonding position of the reinforcing sheet. Once the attachment head reaches the bonding position, a fourth motor starts, driving the attachment head to slide radially towards the PCB board, bonding the reinforcing sheet to the PCB board. During the bonding process, the heating element of the attachment head automatically heats the reinforcing sheet, thus completing the bonding of one reinforcing sheet. It is important to note that before bonding, if the posture of the reinforcing sheet on the attachment head is not conducive to direct bonding, the controller will start a rotary motor to adjust the posture of the reinforcing sheet according to the image data from the second positioning camera, ensuring that the posture meets the bonding requirements.

[0040] Then the attachment head continues to pick up and feed the reinforcing sheets to the second feeding station. This process is repeated automatically until all the reinforcing sheets are attached. Finally, the PCB board is transferred from the PCB board mounting plate to the first feeding station and then picked up by the unloading equipment.

[0041] The embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. For those skilled in the art, after learning the contents of the present invention, several equivalent changes and substitutions can be made without departing from the principle of the present invention. These equivalent changes and substitutions should also be considered to fall within the protection scope of the present invention.
